Plan a feature or initiative: default product flow (idea → PRD → plan), feature flow with formal spec + task-type, sources flow (MRD → BRD → URD), or ISO 29148 cascade (BRS → StRS → SyRS → SRS). Use for 'plan the X redesign', 'create a roadmap', 'plan a new feature'. Pick a flow with --track. Not for recording a decision — use /archcore:decide.
